Laser marker

Abstract

A light source unit holder, on which a light source unit is mounted, is rockably supported via a gimbal mechanism, and projects a brightline using a laser beam emitted from the light source unit, the gimbal mechanism includes a pair of shafts that support the rocking body rockably from both sides thereof, a spherical-body receiving hole is formed at a tip of the pair of shafts, and also in the rocking body a spherical-body receiving hole is formed in a position to which the tips of the pair of shafts face, and a spherical body is interposed between the spherical-body receiving hole of the pair of shafts and the spherical-body receiving hole of the rocking body, the latter spherical-body receiving hole facing the spherical-body receiving hole of each shaft, so that the rocking body is rockably supported, for preventing dynamic sensitivity of the gimbal mechanism from decreasing.

1 . A laser marker, wherein a light source unit holder to which a light source unit is mounted is rockably supported via a gimbal mechanism, the laser marker projecting a brightline using a laser beam emitted from the light source unit, wherein
 the gimbal mechanism includes a pair of shafts that support a rocking body rockably from both sides thereof,   a spherical-body receiving hole is formed at a tip of the pair of shafts, and also in the rocking body a spherical-body receiving hole is formed in a position to which tips of the pair of shafts face, and   a spherical body is interposed between the spherical-body receiving hole of the pair of shafts and the spherical-body receiving hole of the rocking body, the latter spherical-body receiving hole facing the spherical-body receiving hole of each shaft, so that the rocking body is rockably supported.   
   
   
       2 . The laser marker according to  claim 1 , wherein the spherical-body receiving holes of the pair of shafts and the spherical-body receiving holes of the rocking body comprise a conical-shaped depression. 
   
   
       3 . The laser marker according to  claim 1 , wherein the pair of shafts are mounted on a gimbal frame that is integral with a base of the laser marker, and the rocking body is an intermediate rocking body that rockably supports the light source unit holder. 
   
   
       4 . The laser marker according to  claim 3 , wherein each of the pair of shafts is screwed into a screw hole formed in the gimbal frame. 
   
   
       5 . The laser marker according to  claim 1 , wherein the spherical body comprises a steel ball.
